In looking at some of the code written by the master, can always see our small white usually do not use the key words, once, two times, three times, can not always be shady, and now summarize the daily development of commonly used key words function:

#include using namespace Std;Class Test{Privateconst int A; Const member variables can only be initialized in the constructor's member initialization list, not in the body of the function, or elsewherestatic int b; Static member variables need to be

Today I want to write a static constant, and I will write it: Public static const int pagesize = 15; When the result is compiled, an error occurs: static and const cannot be used together. Oh, originally, const is an implicit static statement and

The static keyword has at least N functions:(1) The static variable in the function body applies to this function body. Unlike the auto variable, the memory of this variable is allocated only once, therefore, the value remains the value of the

1. Const and READONLYConst , whose decorated field can only be initialized when it declares itself.Readonly is a read-only variable that belongs to a runtime variable and can change its value when the class is initialized. A field of this type that

Const is a C-language keyword that restricts a variable from being allowed to be changed. The use of const can improve the security and reliability of the program to a certain extent, and it can also help to understand the role of Const clearly when

Basic definition:Const is a read-only meaning and is used only in declarations;static generally has 2 functions, which specify scope and storage mode .For local variables, static is defined as static storage , the initial value of each invocation is
